Status of the Canadian Penning Trap mass spectrometer at the Argonne National Laboratories

Abstract

The Canadian Penning Trap (CPT) mass spectrometer has been modified and reassembled at the ATLAS facility of the Argonne National Laboratory. It is currently being commissioned there. With this apparatus we expect to be able to measure the masses of a wide variety of nuclides having half-lives greater that 0.1 s, to an accuracy of better than 10 ppb of the mass. The planned program of measurements is aimed at improving our knowledge of the nuclear mass surface in general and to provide precise mass data of relevance to tests of the Standard Model and fundamental symmetries. This report describes the current status of the instrument.
